Understanding the world in which we live.

There are quite a few on Amazon, I used to buy them for my grandson as it was a more enjoyable way of learning. The horrible history stories are very successful.

Yes, it is important for children to learn history, BUT it must be accurate. It's easy for history to be taught from a particular point of view, and this causes prejudice. We live in precarious times and you are dealing with the future generation, so be wise in your choice.
I was brought up on the Ladybird series of books with Janet and John, who lived very middle class lives. Not really relevant to todays children.

Judging by my eldest granddaughter (A* in A level history) Horrible Histories was pretty successful in getting her started. 😂

Aren't you busy enough? As an ex-teacher myself I adapted resources to suit my classes. I certainly had no time to make my own.
Your option is to stay where you are putting your own slant on things to encourage your students to think for themselves, or you can leave and go into educational publishing.
I can' think of any teachers who could do both these things well.

What about Horrible Histories there’s loads of books and stage shows I remember taking my grandkids about 13 years ago
There’s also a whole series of stories about various historical characters I can’t remember the series name though

Just checked on Amazon and there’s really a lot of good looking history stories for various ages including events people black history loads of them I m surprised you haven’t found them I really don’t think there’s a gap in the market at all

The historical characters series is Horribly Famous. They’re great, as are the Horrible Histories/Geography/Science books. They really got the grandsons interested in what, without them, they might have dismissed as boring old facts. They have board games, various cards and jigsaws from the series as well. They’ve actually taught me a lot.

Historical fiction for children has always been popular. Is there a particular era that you feel has been neglected?

These books fired our children’s imagination.
I doubt they could be improved on.

My 11 year old grandson loves Horrible Histories and has learned a lot from them. There's certainly a lack of History teaching. Just watch any quiz show, "Who was the monarch during WWII?" "Queen Victoria?" isn't too far fetched.

Agreed.

Where do you feel the gap is, OP?

Sun Horse Moon Horse, and Eagle of the Ninth by Rosemary Sutcliffe are properly researched and entertaining too.

I think this author goes a long way to stimulate curiosity about the human past without losing historical credibility.
